2007 Pontiac Grand PRIX Owners Manual

Tire Inflator Kit (GXP) Your vehicle may have a tire inflator kit. The kit uses a liquid tire sealant and air at the same time to seal small punctures in the tread area of the tire. Be sure to read and follow all the tire inflator kit instructions.

The kit includes the following:

A. Air Compressor B. Tire Sealant Canister C. Air Compressor Accessory Plug

D. On/Off Switch

E. Air Pressure Gage F. Air Compressor

Inflator Hose

G. Sealant

Filling Hose

424

If the flat tire is due to a slow leak caused by a nail or other similar road hazard, the tire inflator kit may be used to temporarily repair the damaged tire. After temporarily repairing a tire using the tire inflator kit, it is recommended to take your vehicle to an authorized GM dealer within 100 miles (161 kilometers) of driving to have the tire inspected and repaired. If the sealant isn’t removed from the tire within a 100 miles (161 kilometers) of driving, it is more likely that the tire and tire pressure monitoring sensor may get damaged and have to be replaced.

Accessing the Tire Inflator Kit To access the tire inflator kit, do the following: 1. Open the trunk. See Trunk on page 96

for more information.

2. Locate the tire inflator kit by lifting up the

carpet.

3. Remove the inflator kit cover by turning the center nut counterclockwise.

425

Tire Sealant The kit contains a liquid sealant that when injected into a flat tire, may temporarily repair nail holes or cuts in the tread area of the tire. The tire sealant cannot repair tire damage caused while driving on a flat tire or a tire that has had a “blow out” or a tire that has punctures in the sidewall areas. The tire sealant solution is to be used for a single tire and can only be used once. Check the tire sealant expiration date on the sealant canister. The sealant may not be as effective beyond the expiration date. If needed, see your GM dealer for a replacement canister. After temporarily repairing a tire using the tire sealant, take your vehicle to an authorized GM dealer to have the tire inspected and repaired.

4. Remove the inflator kit by pulling it straight

out of the foam container.

426

Using the Tire Inflator Kit To use the tire inflator kit, do the following: 1. Place the inflator kit on the ground and unwrap

the sealant filling hose from the compressor. 2. Remove the air compressor accessory plug from the unit. To do this, pull the top portion of the wrapped cord out first, then the bottom, then unsnap the plug. Do not insert the plug into an accessory outlet yet.

3. Remove the valve stem cap from the flat tire

by turning it counterclockwise. If an object, such as a nail, has penetrated the tire, do not remove it.

4. Attach the sealant filling hose (A) onto the tire

valve stem. Turn it clockwise until it is tight. Make sure the inflator kit on/off switch (B) is in the O (off) position.

5. Plug the air compressor accessory plug (C)

into an accessory power outlet in the vehicle. See Accessory Power Outlet(s) on page 156
for more information.

427

7. Move the inflator kit switch to the I (on)

position. The inflator kit will force sealant and air into the tire. Sealant may leak from the puncture hole until the vehicle is driven and the hole has sealed.

8. Make sure there is a proper connection

between the tire valve stem and the sealant filling hose by looking at the air pressure gage. If there is not a pressure reading while the compressor is running, the connection between the inflator kit and the tire is bad. Check the attachment between the sealant filling hose and the tire valve stem.

{CAUTION:

Idling the engine in a closed-in place or with the climate control system off can cause deadly carbon monoxide (CO). See Engine Exhaust on page 119.

6. Start the vehicle. See Starting the Engine on

page 107 for more information. The vehicle must be running while using the air compressor.

{CAUTION:

Inflating something too much can make it explode, and you or others could be injured. Be sure to read the inflator instructions, and inflate the tire to its recommended pressure. Do not exceed 36 psi (248 kPa).

428

9. Inflate the tire up to the recommended

inflation pressure, found on the Tire and Loading Information label located on the vehicle’s center pillar (B-pillar) below the vehicle’s door latch, using the air pressure gage on the top of the unit as a guide. The pressure gage reading is slightly high while the compressor is on. Turn the compressor off to get an accurate pressure reading.

If the recommended pressure cannot

Notice: be reached after 15 minutes, the vehicle should not be driven farther. Damage to the tire is severe and the sealant will not be effective. Remove the air compressor plug from the accessory power outlet and unscrew the inflating hose from the tire valve. See Roadside Assistance Program on page 498.

10. Move the inflator kit switch to the O (off) position once the correct tire pressure is obtained.

11. Turn off the engine. 12. Unplug the air compressor accessory plug

from the accessory power outlet in the vehicle.

13. Disconnect the sealant filling hose from the

tire valve stem, by turning it counterclockwise, and replace the tire valve stem cap. Be careful when handling the tire inflator components as they may be hot after usage. 14. Wrap the sealant filling hose around the air compressor channel to stow it in its original location.

15. Stow the air compressor accessory plug back in the air compressor. To do this, wrap the air compressor accessory plug, snap in the plug, and then push in the bottom and then the top of the wrapped air compressor accessory plug.

429

16. If the flat tire was

able to inflate to the recommended inflation pressure, remove the maximum speed label from the sealant canister.

Place it in a highly visible location such as the inside of the upper left corner of the windshield or to the face of the radio/clock. The maximum speed label reminds you to drive cautiously and not to exceed 55 mph (90 km/h) until you have the damaged tire inspected and repaired.

{CAUTION:

Storing the tire inflator kit or other equipment in the passenger compartment of the vehicle could cause injury. In a sudden stop or collision, loose equipment could strike someone. Store the tire inflator kit in the proper place.

17. Return the equipment to the proper storage

location in the trunk of your vehicle.

430

18. Immediately drive the vehicle 5 miles (8 km)

to distribute the sealant evenly in the tire. Stop at a safe location and check the tire pressure. Refer to Steps 1 through 8
under “Using the Air Compressor without Sealant” next in this section. If the tire pressure has fallen more than 10 psi (68 kPa) below the recommended inflation pressure, stop driving the vehicle. The tire is too damaged for the sealant to work. See Roadside Assistance Program on page 498. If the tire pressure has not dropped more than 10 psi (68 kPa) from the recommended inflation pressure, you can inflate the tire back up to the recommended inflation pressure.

19. Dispose of the sealant canister at a local GM dealer or in accordance with your local state codes and practices. After using the sealant canister, replace it with a new canister from a GM dealer.

20. After temporarily repairing a tire with the

emergency flat tire repair kit, take your vehicle to an authorized GM dealer to have the tire inspected and repaired.

Changing a Flat Tire If a tire goes flat, avoid further tire and wheel damage by driving slowly to a level place. Turn on your vehicle’s hazard warning flashers. See Hazard Warning Flashers on page 134 for more information.

{CAUTION:

Changing a tire can be dangerous. The vehicle can slip off the jack and roll over or fall on you or other people. You and they could be badly injured or even killed. Find a level place to change your tire. To help prevent the vehicle from moving:

1. Set the parking brake firmly. 2. Put the shift lever in PARK (P).

CAUTION:

(Continued)

CAUTION:

(Continued)

3. Turn off the engine and do not restart

while the vehicle is raised.

4. Do not allow passengers to remain in

the vehicle.

To be even more certain the vehicle will not move, you should put blocks at the front and rear of the tire farthest away from the one being changed. That would be the tire, on the other side, at the opposite end of the vehicle.

435

When your vehicle has a flat tire, use the following example as a guide to assist you in the placement of wheel blocks.

The following information will tell you next how to use the jack and change a tire.

436

Removing the Spare Tire and Tools The equipment needed to change a tire is located in the trunk. 1. Open the trunk. See Trunk on page 96 for

more information.

2. Remove the convenience net, if equipped, by

removing the net hook attachments.

3. Lift up the carpet.

4. Turn the center nut

on the compact spare tire cover counterclockwise to remove it.

5. Remove the cover. 6. Remove the compact spare tire. See Compact Spare Tire on page 447 for more information.

7. Turn the nut holding the jack counterclockwise

and remove it. Then remove the jack and wrench.

8. The tools you will be using include the

jack (A), extension and protector/guide (B) and the wheel wrench (C).

437

Removing the Flat Tire and Installing the Spare Tire Your vehicle may have aluminum wheels. If so, you will see exposed stainless steel wheel nuts. Use the wheel wrench to loosen all the wheel nuts. Do not remove them yet. Or, your vehicle may have steel wheel covers.

To remove the steel wheel covers and wheel nut caps, loosen the plastic nut caps with the wheel wrench in a counterclockwise direction. If needed, you can finish loosening them with your fingers. The plastic nut caps will not come off. Use the flat end of the wheel wrench and pry along the edge of the cover until it comes off. The edge of the wheel cover could be sharp, so do not try to remove it with your bare hands. Do not drop the cover or lay it face down, as it could become scratched or damaged.

438

Once you have removed the wheel cover, use the following procedure to remove the flat tire and install the spare tire.

1. Set the park brake firmly. Before preceding it is recommended that you perform a safety check. See Changing a Flat Tire on page 435 for more information.

2. Turn the wheel wrench once on each wheel nut to loosen them. Do not remove them yet.

3. Find the jacking location located on the

underside of the rocker trim using the diagram. For jacking at the vehicle’s front location, put the jack lift head (C) about 6 inches (15 cm) from the rear edge of the front wheel opening (B). Line up the jack with the arrow (A) as shown.

439

4. Put the compact spare tire near you.

{CAUTION:

Getting under a vehicle when it is jacked up is dangerous. If the vehicle slips off the jack you could be badly injured or killed. Never get under a vehicle when it is supported only by a jack.

{CAUTION:

Raising your vehicle with the jack improperly positioned can damage the vehicle and even make the vehicle fall. To help avoid personal injury and vehicle damage, be sure to fit the jack lift head into the proper location before raising the vehicle.

For jacking at the vehicle’s rear location, put the jack lift head (B) about 9 inches (23 cm) from the front edge of the rear wheel opening (C). Line up the jack with the arrow (A) as shown.

440

{CAUTION:

Lifting a vehicle and getting under it to do maintenance or repairs is dangerous without the appropriate safety equipment and training. The jack provided with your vehicle is designed only for changing a flat tire. If it is used for anything else, you or others could be badly injured or killed if the vehicle slips off the jack. Use the jack provided with your vehicle only for changing a flat tire.

5. Raise the vehicle by turning the jack handle clockwise. Raise the vehicle far enough off the ground for the compact spare tire to attach to the vehicle.

441

6. Remove all wheel nuts and take off the

flat tire.

{CAUTION:

Rust or dirt on the wheel, or on the parts to which it is fastened, can make the wheel nuts become loose after time. The wheel could come off and cause an accident. When you change a wheel, remove any rust or dirt from the places where the wheel attaches to the vehicle. In an emergency, you can use a cloth or a paper towel to do this; but be sure to use a scraper or wire brush later, if needed, to get all the rust or dirt off.

7. Remove any rust or dirt from the wheel bolts, mounting surfaces and spare wheel.

8. Install the compact spare tire.

{CAUTION:

Never use oil or grease on studs or nuts. If you do, the nuts might come loose. Your wheel could fall off, causing a serious accident.

442

9. Reinstall the wheel

nuts with the rounded end of the nuts toward the wheel. Tighten each nut by hand until the wheel is held against the hub.

10. Lower the vehicle by turning the jack handle counterclockwise. Lower the jack completely.

443

11. Tighten the wheel

nuts firmly in a crisscross sequence as shown.

Notice: Wheel covers will not fit on your compact spare. If you try to put a wheel cover on the compact spare, you could damage the cover or the spare. Do not try to put the wheel cover on the compact spare tire. It will not fit. Store the wheel cover in the trunk until the flat tire is repaired or replaced.

{CAUTION:

Incorrect wheel nuts or improperly tightened wheel nuts can cause the wheel to come loose and even come off. This could lead to an accident. Be sure to use the correct wheel nuts. If you have to replace them, be sure to get new GM original equipment wheel nuts. Stop somewhere as soon as you can and have the nuts tightened with a torque wrench to the proper torque specification. See Capacities and Specifications on page 466
for wheel nut torque specification.

Improperly tightened wheel nuts can

Notice: lead to brake pulsation and rotor damage. To avoid expensive brake repairs, evenly tighten the wheel nuts in the proper sequence and to the proper torque specification. See Capacities and Specifications on page 466 for the wheel nut torque specification.

444

Storing a Flat or Spare Tire and Tools

{CAUTION:

Storing a jack, a tire, or other equipment in the passenger compartment of the vehicle could cause injury. In a sudden stop or collision, loose equipment could strike someone. Store all these in the proper place.

After the compact spare tire is put on the vehicle, store the flat tire in the trunk. Use the following procedure to secure it in the trunk. When storing a full-size tire, use the extension and protector/guide, located in the foam holder, to help avoid wheel surface damage.

To store a full-size tire, do the following: 1. Install the tools in their original location in the

trunk area and secure.

2. Place the tire in the trunk with the valve stem

facing down, and the protector/guide placed through a wheel bolt hole.

3. Remove the protector and attach the retainer

securely.

4. Place the protector/guide back in the foam

holder when putting the compact spare back in the trunk. Store the cover as far forward as possible.

The compact spare tire is for temporary use only. Replace the compact spare tire with a full-size tire as soon as possible. See Compact Spare Tire on page 447 for more information. Use the following as a guide for storing the compact spare tire and tools.

Full-Sized Spare Tire

Notice: When the compact spare is installed, do not take your vehicle through an automatic car wash with guide rails. The compact spare can get caught on the rails. That can damage the tire and wheel, and maybe other parts of your vehicle. Do not use the compact spare on other vehicles. And do not mix the compact spare tire or wheel with other wheels or tires. They will not fit. Keep the spare tire and its wheel together. Notice: Tire chains will not fit your compact spare. Using them can damage your vehicle and can damage the chains too. Do not use tire chains on your compact spare.

Compact Spare Tire Although the compact spare tire was fully inflated when the vehicle was new, it can lose air after a time. Check the inflation pressure regularly. It should be 60 psi (420 kPa). After installing the compact spare on the vehicle, you should stop as soon as possible and make sure the spare tire is correctly inflated. The compact spare is made to perform well at speeds up to 65 mph (105 km/h) for distances up to 3,000 miles (5 000 km), so you can finish your trip and have the full-size tire repaired or replaced where you want. You must calibrate the tire inflation monitor system, if your vehicle has this feature, after installing or removing the compact spare. See Tire Pressure Monitor System on page 409. The system may not work correctly when the compact spare is installed on the vehicle. Of course, it’s best to replace the spare with a full-size tire as soon as you can. The spare will last longer and be in good shape in case you need it again.

447

Appearance Care

Cleaning the Inside of Your Vehicle Your vehicle’s interior will continue to look its best if it is cleaned often. Although not always visible, dust and dirt can accumulate on your upholstery. Dirt can damage carpet, fabric, leather, and plastic surfaces. Regular vacuuming is recommended to remove particles from your upholstery. It is important to keep your upholstery from becoming and remaining heavily soiled. Soils should be removed as quickly as possible. Your vehicle’s interior may experience extremes of heat that could cause stains to set rapidly. Lighter colored interiors may require more frequent cleaning. Use care because newspapers and garments that transfer color to your home furnishings may also transfer color to your vehicle’s interior. When cleaning your vehicle’s interior, only use cleaners specifically designed for the surfaces being cleaned. Permanent damage may result from using cleaners on surfaces for which they were not intended. Use glass cleaner only on glass.

448

If you use abrasive cleaners when

Remove any accidental over-spray from other surfaces immediately. To prevent over-spray, apply cleaner directly to the cleaning cloth. Notice: cleaning glass surfaces on your vehicle, you could scratch the glass and/or cause damage to the integrated radio antenna and the rear window defogger. When cleaning the glass on your vehicle, use only a soft cloth and glass cleaner. Many cleaners contain solvents that may become concentrated in your vehicle’s breathing space. Before using cleaners, read and adhere to all safety instructions on the label. While cleaning your vehicle’s interior, maintain adequate ventilation by opening your vehicle’s doors and windows. Dust may be removed from small buttons and knobs using a small brush with soft bristles. Your dealer has a product for cleaning your vehicle’s glass. Should it become necessary, you can also obtain a product from your dealer to remove odors from your vehicle’s upholstery.

Do not clean your vehicle using the following cleaners or techniques: (cid:127) Never use a knife or any other sharp object to

remove a soil from any interior surface.

(cid:127) Never use a stiff brush. It can cause damage

to your vehicle’s interior surfaces. (cid:127) Never apply heavy pressure or rub

aggressively with a cleaning cloth. Use of heavy pressure can damage your interior and does not improve the effectiveness of soil removal.

(cid:127) Use only mild, neutral-pH soaps. Avoid

laundry detergents or dishwashing soaps with degreasers. Using too much soap will leave a residue that leaves streaks and attracts dirt. For liquid cleaners, about 20 drops per gallon (3.78 L) of water is a good guide.

(cid:127) Do not heavily saturate your upholstery while

cleaning.

(cid:127) Damage to your vehicle’s interior may result from the use of many organic solvents such as naptha, alcohol, etc.

Fabric/Carpet Cleaning Fabric/Carpet Use a vacuum cleaner often to get rid of dust and loose dirt. Wipe vinyl, leather, plastic, and painted surfaces with a clean, damp cloth. Your dealer has cleaners for the cleaning of fabric and carpet. They will clean normal spots and stains very well. If the vehicle has the Ultra Lux® suede fabric, follow the listed procedures except do not use any solvents or dry cleaning products. Here are some cleaning tips: (cid:127) Always read the instructions on the cleaner

(cid:127) Clean up stains as soon as you can, before

they set.

(cid:127) Carefully scrape off any excess stain. (cid:127) Use a clean cloth or sponge, and change to a clean area often. A soft brush may be used if stains are stubborn.

(cid:127) To avoid forming a ring on fabric after spot cleaning, clean the entire area immediately or it will set.

449

Most stains can be removed with club soda water. To clean, use the following instructions: 1. For liquids: blot with a clean, soft white cloth.

For solids: remove as much as possible and then vacuum or brush.

2. Apply club soda water to a clean, soft white cloth. Do not over-saturate; the cloth should not drip water.

3. Clean the entire area. Avoid getting the fabric

too wet.

4. Start cleaning from the seams into the stain to

avoid a ring effect.

5. Continue cleaning, using a clean area of the

cloth each time it becomes soiled.

6. When the stain is removed, blot the cleaned area with another dry clean, soft white cloth.

Using Cleaner on Fabric 1. First, try the cleaner in an inconspicuous area

to make sure the cleaner does not affect the color of the fabric.

2. For liquids: blot the stain with a clean, soft

white cloth. For solids: remove as much as possible and then vacuum or brush.

450

3. Spray a small amount of the cleaner onto a

clean, soft white cloth. Do not apply spray directly to the fabric.

4. Start cleaning from the seams into the stain to

avoid a ring effect.

5. Continue cleaning, using a clean area of the

cloth each time it becomes soiled.

6. When the stain is removed, blot the cleaned area with another dry clean, soft white cloth. 7. If the cleaner leaves a ring effect, follow up with the club soda water instructions given earlier in this section.

Special Fabric Cleaning Problems Stains caused by such things as catsup, coffee, tea, milk, fruit, fruit juice, jelly, cheese, chocolate, vomit, urine, and blood can be removed using the club soda water instructions given earlier in this section. If an odor lingers after cleaning vomit or urine, treat the area with a water and baking soda solution: 1 teaspoon (5 ml) of baking soda to 1 cup (250 ml) of lukewarm water. Let dry.

Stains caused by oil and grease can be cleaned with an approved GM cleaner and a clean, white cloth. 1. Carefully scrape off excess stain. 2. Clean with cool water and allow to dry

completely.

3. If a stain remains, follow the cleaner

instructions described earlier.

Leather A soft cloth dampened with water may be used to remove dust. If a more thorough cleaning is necessary, a soft cloth dampened with a mild soap solution can be used. Allow the leather to dry naturally. Do not use heat to dry. Never use steam to clean leather. Never use spot lifters or spot removers on leather. Many commercial leather cleaners and coatings that are sold to preserve and protect leather may permanently change the appearance and feel of your leather and are not recommended. Do not use silicone or wax-based products, or those containing organic solvents to clean your vehicle’s interior because

they can alter the appearance by increasing the gloss in a non-uniform manner. Never use shoe polish on your leather.

Ultra Lux Suede Cleaning Ultra Lux Suede Use a mild solution of lukewarm water and a neutral dish soap on a soft cloth or sponge. For the following stains, follow these instructions:

Coffee, Tea, and Milk: Blot with a clean, soft, white cloth. Then clean with mild soapy water and a clean white cloth.

Cosmetics: Clean with mild soapy water and a clean white cloth.

Jelly, Syrup, and Fruit: Remove most of the solids, then clean with warm tap water and a clean white cloth.

Oil and Grease: Sprinkle baking soda on the spot, brush, then wipe with a clean white cloth.

451

Instrument Panel, Vinyl, and Other Plastic Surfaces A soft cloth dampened with water may be used to remove dust. If a more thorough cleaning is necessary, a clean soft cloth dampened with a mild soap solution can be used to gently remove dust and dirt. Never use spot lifters or removers on plastic surfaces. Many commercial cleaners and coatings that are sold to preserve and protect soft plastic surfaces may permanently change the appearance and feel of your interior and are not recommended. Do not use silicone or wax-based products, or those containing organic solvents to clean your vehicle’s interior because they can alter the appearance by increasing the gloss in a non-uniform manner. Some commercial products may increase gloss on your instrument panel. The increase in gloss may cause annoying reflections in the windshield and even make it difficult to see through the windshield under certain conditions.

Care of Safety Belts Keep belts clean and dry.

{CAUTION:

Do not bleach or dye safety belts. If you do, it may severely weaken them. In a crash, they might not be able to provide adequate protection. Clean safety belts only with mild soap and lukewarm water.

Weatherstrips Silicone grease on weatherstrips will make them last longer, seal better, and not stick or squeak. Apply silicone grease with a clean cloth. During very cold, damp weather frequent application may be required. See Recommended Fluids and Lubricants on page 483.

452

Washing Your Vehicle The paint finish on the vehicle provides beauty, depth of color, gloss retention, and durability. The best way to preserve the vehicle’s finish is to keep it clean by washing it often with lukewarm or cold water. Do not wash the vehicle in the direct rays of the sun. Use a car washing soap. Do not use strong soaps or chemical detergents. Be sure to rinse the vehicle well, removing all soap residue completely. Approved cleaning products can be obtained from your dealer. See Vehicle Care/Appearance Materials on page 457. Do not use cleaning agents that are petroleum based, or that contain acid or abrasives. All cleaning agents should be flushed promptly and not allowed to dry on the surface, or they could stain. Dry the finish with a soft, clean chamois or an all-cotton towel to avoid surface scratches and water spotting. High pressure car washes may cause water to enter the vehicle.

Cleaning Exterior Lamps/Lenses Use only lukewarm or cold water, a soft cloth and a car washing soap to clean exterior lamps and lenses. Follow instructions under Washing Your Vehicle on page 453.

Finish Care Occasional waxing or mild polishing of the vehicle by hand may be necessary to remove residue from the paint finish. Approved cleaning products can be obtained from your dealer. See Vehicle Care/Appearance Materials on page 457. Notice: Machine compounding or aggressive polishing on a basecoat/clearcoat paint finish may damage it. Use only non-abrasive waxes and polishes that are made for a basecoat/clearcoat paint finish on your vehicle. The vehicle has a basecoat/clearcoat paint finish. The clearcoat gives more depth and gloss to the colored basecoat. Always use waxes and polishes that are non-abrasive and made for a basecoat/clearcoat paint finish.

453

Foreign materials such as calcium chloride and other salts, ice melting agents, road oil and tar, tree sap, bird droppings, chemicals from industrial chimneys, etc., can damage the vehicle’s finish if they remain on painted surfaces. Wash the vehicle as soon as possible. If necessary, use non-abrasive cleaners that are marked safe for painted surfaces to remove foreign matter. Exterior painted surfaces are subject to aging, weather, and chemical fallout that can take their toll over a period of years. To help keep the paint finish looking new, keep the vehicle in a garage or covered whenever possible.

Windshield and Wiper Blades If the windshield is not clear after using the windshield washer, or if the wiper blade chatters when running, wax, sap, or other material may be on the blade or windshield. Clean the outside of the windshield with a glass cleaning liquid or powder and water solution. The windshield is clean if beads do not form when it is rinsed with water.

Grime from the windshield will stick to the wiper blades and affect their performance. Clean the blade by wiping vigorously with a cloth soaked in full-strength windshield washer solvent. Then rinse the blade with water. Check the wiper blades and clean them as necessary; replace blades that look worn.

If you use strong soaps, chemicals,

Aluminum Wheels Notice: abrasive polishes, cleaners, brushes, or cleaners that contain acid on aluminum or chrome-plated wheels, you could damage the surface of the wheel(s). The repairs would not be covered by your warranty. Use only GM-approved cleaners on aluminum or chrome-plated wheels. Keep the wheels clean using a soft clean cloth with mild soap and water. Rinse with clean water. After rinsing thoroughly, dry with a soft clean towel. A wax may then be applied.

454

Notice: Using chrome polish on aluminum wheels could damage the wheels. The repairs would not be covered by your warranty. Use chrome polish on chrome wheels only. The surface of these wheels is similar to the painted surface of the vehicle. Do not use strong soaps, chemicals, abrasive polishes, abrasive cleaners, cleaners with acid, or abrasive cleaning brushes on them because the surface could be damaged. Do not use chrome polish on aluminum wheels. Notice: If you drive your vehicle through an automatic car wash that has silicone carbide tire cleaning brushes, you could damage the aluminum or chrome-plated wheels. The repairs would not be covered by your warranty. Never drive a vehicle equipped with aluminum or chrome-plated wheels through an automatic car wash that uses silicone carbide tire cleaning brushes. Do not take the vehicle through an automatic car wash that has silicone carbide tire cleaning brushes. These brushes can also damage the surface of these wheels.

Tires To clean the tires, use a stiff brush with tire cleaner. Notice: Using petroleum-based tire dressing products on your vehicle may damage the paint finish and/or tires. When applying a tire dressing, always wipe off any overspray from all painted surfaces on your vehicle.

Sheet Metal Damage If the vehicle is damaged and requires sheet metal repair or replacement, make sure the body repair shop applies anti-corrosion material to parts repaired or replaced to restore corrosion protection. Original manufacturer replacement parts will provide the corrosion protection while maintaining the warranty.

455

Finish Damage Any stone chips, fractures or deep scratches in the finish should be repaired right away. Bare metal will corrode quickly and may develop into major repair expense. Minor chips and scratches can be repaired with touch-up materials available from your dealer. Larger areas of finish damage can be corrected in your dealer’s body and paint shop.

Underbody Maintenance Chemicals used for ice and snow removal and dust control can collect on the underbody. If these are not removed, corrosion and rust can develop on the underbody parts such as fuel lines, frame, floor pan, and exhaust system even though they have corrosion protection.

At least every spring, flush these materials from the underbody with plain water. Clean any areas where mud and debris can collect. Dirt packed in close areas of the frame should be loosened before being flushed. Your dealer or an underbody car washing system can do this for you.

Chemical Paint Spotting Some weather and atmospheric conditions can create a chemical fallout. Airborne pollutants can fall upon and attack painted surfaces on the vehicle. This damage can take two forms: blotchy, ring-shaped discolorations, and small, irregular dark spots etched into the paint surface. Although no defect in the paint job causes this, GM will repair, at no charge to the owner, the surfaces of new vehicles damaged by this fallout condition within 12 months or 12,000 miles (20 000 km) of purchase, whichever occurs first.

Vehicle Identification

Vehicle Identification Number (VIN)

This is the legal identifier for your vehicle. It appears on a plate in the front corner of the instrument panel, on the driver’s side. You can see it if you look through the windshield from outside your vehicle. The VIN also appears on the Vehicle Certification and Service Parts labels and the certificates of title and registration.

Engine Identification The eighth character in the VIN is the engine code. This code will help you identify your vehicle’s engine, specifications, and replacement parts.

Service Parts Identification Label You will find this label in the trunk. It is very helpful if you ever need to order parts. On this label, you will find the following: (cid:127) VIN (cid:127) Model designation (cid:127) Paint information (cid:127) Production options and special equipment Do not remove this label from the vehicle.

458

Electrical System

Add-On Electrical Equipment Notice: Do not add anything electrical to your vehicle unless you check with your dealer first. Some electrical equipment can damage your vehicle and the damage would not be covered by your warranty. Some add-on electrical equipment can keep other components from working as they should. Add-on equipment can drain your vehicle’s battery, even if your vehicle is not operating. Your vehicle has an airbag system. Before attempting to add anything electrical to your vehicle, see Servicing Your Airbag-Equipped Vehicle on page 78.

Headlamp Wiring The headlamp circuit is protected by individual fuses in the underhood fuse block. An electrical overload will cause the fuse to blow. If this happens, have the headlamp system checked right away.

Windshield Wiper Fuses The windshield wiper motor is protected by a circuit breaker and a fuse. If the motor overheats due to heavy snow, etc., the wiper will stop until the motor cools. If the overload is caused by some electrical problem, have it fixed.

Power Windows and Other Power Options Circuit breakers in the fuse panel protect the power windows and other power accessories. When the current load is too heavy, the circuit breaker opens and closes, protecting the circuit until the problem is fixed.

459

Fuses and Circuit Breakers The wiring circuits in the vehicle are protected from short circuits by a combination of fuses, circuit breakers and fusible thermal links in the wiring itself. This greatly reduces the chance of fires caused by electrical problems. Look at the silver-colored band inside the fuse. If the band is broken or melted, replace the fuse. Be sure to replace a bad fuse with a new one of the identical size and rating. Spare fuses and a fuse puller are located in the underhood fuse block. See Underhood Fuse Block later in this section.

Instrument Panel Fuse Block

Some fuses are in a fuse block located on the end of the instrument panel on the passenger side.

To get to the fuse block lift up on the side panel. A fuse usage chart is on the inside of this panel.

Maintenance Schedule

Introduction Important: Keep engine oil at the proper level and change as recommended.

Maintenance Requirements Notice: Maintenance intervals, checks, inspections, replacement parts, and recommended fluids and lubricants as prescribed in this manual are necessary to keep your vehicle in good working condition. Any damage caused by failure to follow scheduled maintenance may not be covered by warranty.

Have you purchased the GM Protection Plan? The Plan supplements your new vehicle warranties. See your Warranty and Owner Assistance booklet or your dealer for details.

470

Your Vehicle and the Environment Proper vehicle maintenance not only helps to keep your vehicle in good working condition, but also helps the environment. All recommended maintenance is important. Improper vehicle maintenance can even affect the quality of the air we breathe. Improper fluid levels or the wrong tire inflation can increase the level of emissions from your vehicle. To help protect our environment, and to keep your vehicle in good condition, be sure to maintain your vehicle properly.

Using the Maintenance Schedule We at General Motors want to help you keep your vehicle in good working condition. But we do not know exactly how you will drive it. You may drive very short distances only a few times a week. Or you may drive long distances all the time in very hot, dusty weather. You may use your vehicle in making deliveries. Or you may drive it to work, to do errands, or in many other ways. Because of all the different ways people use their vehicles, maintenance needs vary. You may need more frequent checks and replacements. So please read the following and note how you drive. If you have any questions on how to keep your vehicle in good condition, see your GM Goodwrench® dealer.

471

This schedule is for vehicles that: (cid:127) carry passengers and cargo within

recommended limits. You will find these limits on the Tire and Loading Information label. See Loading Your Vehicle on page 317.

(cid:127) are driven on reasonable road surfaces within

legal driving limits.

(cid:127) use the recommended fuel. See Gasoline

Octane on page 338.

The services in Scheduled Maintenance on page 473 should be performed when indicated. See Additional Required Services on page 476 and Maintenance Footnotes on page 477 for further information.

{CAUTION:

Performing maintenance work on a vehicle can be dangerous. In trying to do some jobs, you can be seriously injured. Do your own maintenance work only if you have the required know-how and the proper tools and equipment for the job. If you have any doubt, see your GM Goodwrench® dealer to have a qualified technician do the work.

Some maintenance services can be complex. So, unless you are technically qualified and have the necessary equipment, you should have your GM Goodwrench® dealer do these jobs. When you go to your GM Goodwrench® dealer for your service needs, you will know that GM-trained and supported service technicians will perform the work using genuine GM parts.

472

If you want to purchase service information, see Service Publications Ordering Information on page 511. Owner Checks and Services on page 479 tells you what should be checked, when to check it, and what you can easily do to help keep your vehicle in good condition. The proper replacement parts, fluids, and lubricants to use are listed in Recommended Fluids and Lubricants on page 483 and Normal Maintenance Replacement Parts on page 484. When your vehicle is serviced, make sure these are used. All parts should be replaced and all necessary repairs done before you or anyone else drives the vehicle. We recommend the use of genuine GM parts.

Scheduled Maintenance When the CHANGE OIL SOON message comes on, it means that service is required for your vehicle. See DIC Warnings and Messages on page 200. Have your vehicle serviced as soon as possible within the next 600 miles (1 000 km). It is possible that, if you are driving under the best conditions, the engine oil life system may not indicate that vehicle service is necessary for over a year. However, your engine oil and filter must be changed at least once a year and at this time the system must be reset. Your GM Goodwrench® dealer has GM-trained service technicians who will perform this work using genuine GM parts and reset the system.

473

If the engine oil life system is ever reset accidentally, you must service your vehicle within 3,000 miles (5 000 km) since your last service. Remember to reset the oil life system whenever the oil is changed. See Engine Oil Life System on page 353 for information on the Engine Oil Life System and resetting the system. When the CHANGE OIL SOON message appears, certain services, checks, and inspections are required. Required services are described in the following for “Maintenance I” and “Maintenance II.” Generally, it is recommended that your first service be Maintenance I, your second service be Maintenance II, and that you alternate Maintenance I and Maintenance II thereafter. However, in some cases, Maintenance II may be required more often.

Maintenance I — Use Maintenance I if the CHANGE OIL SOON message comes on within 10 months since the vehicle was purchased or Maintenance II was performed. Maintenance II — Use Maintenance II if the previous service performed was Maintenance I. Always use Maintenance II whenever the message comes on 10 months or more since the last service or if the message has not come on at all for one year.

Maintenance Footnotes † The U.S. Environmental Protection Agency or the California Air Resources Board has determined that the failure to perform this maintenance item will not nullify the emission warranty or limit recall liability prior to the completion of the vehicle’s useful life. We, however, urge that all recommended maintenance services be performed at the indicated intervals and the maintenance be recorded. (a) Visually inspect brake lines and hoses for proper hook-up, binding, leaks, cracks, chafing, etc. Inspect disc brake pads for wear and rotors for surface condition. Inspect other brake parts, including calipers, parking brake, etc.

(b) Visually inspect front and rear suspension and steering system for damaged, loose, or missing parts or signs of wear. Inspect power steering lines and hoses for proper hook-up, binding, leaks, cracks, chafing, etc. (c) Visually inspect hoses and have them replaced if they are cracked, swollen, or deteriorated. Inspect all pipes, fittings, and clamps; replace with genuine GM parts as needed. To help ensure proper operation, a pressure test of the cooling system and pressure cap and cleaning the outside of the radiator and air conditioning condenser is recommended at least once a year.

477

(d) Visually inspect wiper blades for wear or cracking. Replace wiper blades that appear worn or damaged or that streak or miss areas of the windshield. (e) Make sure the safety belt reminder light and all belts, buckles, latch plates, retractors, and anchorages are working properly. Look for any other loose or damaged safety belt system parts. If you see anything that might keep a safety belt system from doing its job, have it repaired. Have any torn or frayed safety belts replaced. Also look for any opened or broken airbag coverings, and have them repaired or replaced. The airbag system does not need regular maintenance. (f) Lubricate all key lock cylinders. Lubricate all hinges and latches, including those for the body doors, hood, secondary latch, pivots, spring anchor, release pawl, rear compartment, glove box door, console door, and any folding seat hardware. More frequent lubrication may be required when exposed to a corrosive environment. Applying silicone grease on weatherstrips with a clean cloth will make them last longer, seal better, and not stick or squeak. (g) If you drive regularly under dusty conditions, the filter may require replacement more often.

478

(h) Change automatic transaxle fluid and filter if the vehicle is mainly driven under one or more of these conditions:

− In heavy city traffic where the outside

temperature regularly reaches 90°F (32°C) or higher.

− In hilly or mountainous terrain. − When doing frequent trailer towing. − Uses such as found in taxi, police, or delivery

service.

(i) Drain, flush, and refill cooling system. This service can be complex; you should have your dealer perform this service. See Engine Coolant on page 360 for what to use. Inspect hoses. Clean radiator, condenser, pressure cap, and filler neck. Pressure test the cooling system and pressure cap. (j) Check throttle system for interference or binding and for damaged or missing parts. Replace parts as needed. Replace any components that have high effort or excessive wear. Do not lubricate accelerator or cruise control cables.

(k) A fluid loss in any vehicle system could indicate a problem. Have the system inspected and repaired and the fluid level checked. Add fluid if needed. (l) For supercharged engines only: Have your dealer check the supercharger oil level and add the proper supercharger oil as needed (or every 36 months, whichever occurs first). See Recommended Fluids and Lubricants on page 483. (m) If you drive regularly under dusty conditions, inspect the filter at each engine oil change. (n) Visually inspect belt for fraying, excessive cracks, or obvious damage. Replace belt if necessary.

Owner Checks and Services These owner checks and services should be performed at the intervals specified to help ensure the safety, dependability, and emission control performance of your vehicle. Your GM Goodwrench® dealer can assist you with these checks and services.

Be sure any necessary repairs are completed at once. Whenever any fluids or lubricants are added to your vehicle, make sure they are the proper ones, as shown in Recommended Fluids and Lubricants on page 483.

At Each Fuel Fill It is important to perform these underhood checks at each fuel fill. Engine Oil Level Check Check the engine oil level and add the proper oil if necessary. See Engine Oil on page 350 for further details. Notice: regularly and keep it at the proper level. Failure to keep your engine oil at the proper level can cause damage to your engine not covered by your warranty. Engine Coolant Level Check Check the engine coolant level and add DEX-COOL® coolant mixture if necessary. See Engine Coolant on page 360 for further details.

It is important to check your oil

479

Windshield Washer Fluid Level Check Check the windshield washer fluid level in the windshield washer fluid reservoir and add the proper fluid if necessary.

At Least Once a Month Tire Inflation Check Visually inspect your vehicle’s tires and make sure they are inflated to the correct pressures. Do not forget to check the spare tire. See
